- This is a BIG reason that 16-bit color if far inferior to 24-bit color.
- Anything with lots of grey levels in it will look bad.

- Unfortunately QuickDraw does not support dithering from 24-bit color
- to 16-bit color. If they had supported that, 16-bit color would have
- been much more workable.
